President Abraham Lincoln gave what is probably the most famous speech in American History 145 years ago at the dedication of the cemetery at the Gettysburg battlefield
Thanks to my Madre for finding this segment about these immortal 272 words on the Writer's Almanac. Just select "Wednesday, November 19th" for the entry.
Here's a link to the Library of Congress exhibition with all the stuff you need: full text of the speech, the only known photo of President Lincoln at Gettysburg, details on preservation techniques, and more.
Now that you don't have to memorize it or present it in front of the class, take a minute and read the speech on your own terms and derive your own meaning from this magnificent oration.
